Comments: Reported in a Chinese young adult and his father in a heterozygous form. They both had a haematological phenotype of mild α+ thalassemia trait with low-normal limit of MCV and normal Hb A2. RNA analysis showed markedly decreased levels of α-globin mRNA and the presence of a small amount of mutant mRNA.

We follow the HGVS sequence variant nomenclature and IUPAC standards.
